It sounds like Rob Kardashian is about to become a full blown gym rat!

It's not exactly a secret that the reality star has been struggling with his weight recently, as he reportedly left his sister Kim Kardashian's Italian wedding early because he didn't want to be in family photos!

As we previously reported, Britney Spears' baby daddy has requested an increase in his $20K a month child support stipend. While it's said that Godney isn't THRILLED at the request, she's letting her poppa negotiate a deal with KFed.

And it appears that negotiations are well under way, though Mr. Spears is NOT impressed with his former son-in-law!
